Heat generation increases cryocooler temperature, thereby reducing efficiency, reliability, and lifetime. Technology Applications, Inc. (TAI), with the support of CSA Engineering, Inc., developed a multi-axis Thermally Conductive Vibration Isolation System (TCVIS) for cryocoolers under a SBIR Phase II program for the Space Vehicles Directorate of AFRL (Contract No. F29601-97-C-0114).

Quench characteristics of 6 T conduction

Conduction-cooled superconducting magnets are cooled by cryocooler alone through the conductive thermal links. The limited refrigeration capacity and conductive cooling make the magnets more prone to quench. We have studied the quench characteristics of a 6 T conduction-cooled NbTi magnet system in detail in this paper. The NbTi magnet has been designed for 102 A with 31% current margin to

Cryocoolers for space applications — Cryogenic

A gas is forced through a thermally isolated porous plug or throttle valve by a mechanical compressor unit leading to isenthalpic cooling. Although this is an irreversible process, with correspondingly low efficiency, J-T coolers are simple, reliable, and have low electrical and mechanical noise levels.

Computer cooling

Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as central processing units (CPUs), chipsets, graphics cards, and hard disk drives.
